PHP - Activation Form Access Restriction

Hello everybody  ,
This is my first topic here and I hope I will find the solution for my problem.
I want to restrict access to file (for exemple: http://www.mysite.com/files/file0000.zip) to a just a specific IP that will be read from the database. And also store all other IPs trying to access this file.
Can this be done, maybe through some php and htaccess?

Thank you for any help or any other ideas.

hi once again, i got a form that uploads an image, checks  formats and all that.. i need to add the filesize restriction.
something like this:

define ("max_size","20"); //<- 20kb size
$size=filesize($_FILES['image']['tmp_name'])

if ($size > max_size*1024){
echo "too big filesize";
} else {
  //......
}



how do i put that code, into this code? :

<?php

$allowedfiletypes = array("jpeg","jpg","gif","png");
$uploadfolder = "uploads/" ;
$thumbnailheight = 100; //in pixels
$thumbnailfolder = $uploadfolder."thumbs/" ;


$action = $_POST['action'];
if ($action == "upload") {
    //echo "<p>Uploading image... " ;

    if(empty($_FILES['uploadimage']['name'])){
        echo '<script type="text/javascript"> {alert("Pasirinkite faila");} </script>';
    } else {
        $uploadfilename = $_FILES['uploadimage']['name'];
        $fileext = strtolower(substr($uploadfilename,strrpos($uploadfilename,".")+1));

        if (!in_array($fileext,$allowedfiletypes)) { 
echo '<script type="text/javascript"> {alert("Blogas failo tipas");} </script>';

any ideas?
thanks

How do I make it so if I get the question right, I have access to view the next page?
For example, if I get this question right in index-1.php correct, it would take me to index-2.php (like in the script below),
but if you don't get the question correct in index-1.php, you cannot have access/view index-2.php.

Why I need this?  Well, if you change the URL http://--------/index-1.php to http://--------/index-2.php, you can easily go from index-1.php to index-2.php without having to answer the question correctly.

index-1.php:
<?php
if(isset($_POST['submit'])){

$number = $_POST['number'];
if ($number == "elephant"){
header("Location: http://localhost/index-2.php");
exit();}
}
?> 

<html>
 <head>
  <title>PHP Test</title>
 </head>
 <b>LEVEL 1</b>
 <body>
 <p>
<font face="Courier New">c291cmNl</font>
</p>
 <br/></body>
</html>

<form action="<?php echo $_SERVER['PHP_SELF'];?>" method="post">
  Answer: <!-- "elephant" --> <input type="text" name="number" /><br />
</select>
<input name="submit" type="submit">
</form>

Thanks

Hi all,
I have been working on this and maybe you guys can help. All I need to do is be able to open a access form with php. I have tried a couple of diffrent things but nothing is working. What I have right now is $app = new COM("Access.Application");
    $app->OpenCurrentDatabase("C:\Documents and Settings\Ian\Desktop\TestData.accdb");
    $app->Application->Run("OpenAccForm");
    //$app->DoCmd->OpenForm("Test Data");
    //$app->Visible = "Yes";
    print "Loaded Access, version {$app->Visible}\n";
Any help is appreciated. Right now It opens access but is not viable. I know it is opening access because it is in the processes tab in task manager.
